vision of a unitary structure of the auto-- mobile type, which, together with a second unit possessing characteristic features, may be combined to form a combination structure, capable of performing definite functions. I have illustrated the physical embodiment of this conception in several dif-' ferent forms in the drawings, wherein I depict a wagon, a mowing machine, a grain drill, a hay rake, and a roller, all farm implements, and wherein the same unitary structure is illustrated in combination with a second unit of characteristic features.

The invention consists essentially in cer- -tain novel combinations and arrangements of parts whereby the tractor is adapted for use with different and various implements, and in the adjustability of parts thereto.

Figural is a side elevation of a tractor embodying the invention. Fig. 2 is a front view of Fig. 1. 'Fig. 3 is a rear view. Fig. 4'is a plan view of Fig. 1. Fig. 5 is an enlarged rear elevation shgwing a, wagon bolster forming part of the implement when.

used as .afvehicle for transporting goods. Fig; 6 is a sectional view taken transversely through the bolster .especially to show the" pipe rolle r which forms a part of the bolster. Fig.7 illustrates the lever mechanism for the transmission gearing of the automobile. Fig. 8 is a plan view of the transmission gearing of Fig. 7. Fig. 9 is a transverse sectional view of one of the drive wheels audits sprocket. Fig. 10 is asectional detail view showing the mode of attaching the tractor to an implement. Fig. 11 shows the tractor attached to and forming part of a vehicle or wagon. Fig. 12 ,shows the same tractor converted for use with a mowing machine. Fig. 13 discloses the unitary structure of the tractor forming an integral part of a grain drill. Fig. 14 depicts the tractor providing the propulsive force-for a hay rake. Fig. 15 illustrates the tractor when used in conjunction with a land-roller. The form of the invention as embodied in Figs. 1, 2, 3, 4, for instance illustrates a ve-' the driving wheels 2 and 3 upon which are supported, by means of the axles or shafts 4 and 5, the front U shaped frame 6, the side hiclehaving the front steering wheels 1 and bars 7 constituting a rear frame, and the transverse bars 8, 8 forming constituent parts: of an intermediate transverse frame extending at each side of the main frame. Themain, or front frame, has a deck or floor 9 constructed of suitablematerial, and the frame members are preferably made up of angle iron, to combine lightness and strength of material. The mam frame, the rear frame and the extension frame are all bolted together, as usual, but it will be apparent that, as will be described hereinafter, the rear axle 5 and driving wheels 2, 3, 111113- trated in Fig. 4 may be removed and other elements of this nature substituted therefor, to adapt the tractor for use with other implements. y

Fig. 10 snows in detail section the manner of attaching the bars 7 to the axle 5, a yoke or clip 10 being passed around the cylindrical tubular axle 5, and secured by nuts 11.

The front axle 4 and steering wheels 1, 1, may be revolved upon the center 12 by means of the cables 13 13 which are passed around the drum 14, and. actuated by the steering device 15 from the wheel 16', the latter befuel from the tank 17 ,and the power of the engine is transmitted through the'following I train of mechanism and ears. The counter shaft -18 at the side of t elmotoris rotated from the crank shaft of the engine through the medium of'the small, gears 19 and 20, the latter on the shaft 18. By means of the sprocket 21 on shaft 18, the sprocket chain 22, and the sprocket wheel 23 on shaft 24 are rotated. The shaft 24 is the transmis-.' sion shaft and is equipped with an independent drive for each of the traction or'driving" wheels 2, 3. The shaft 24 is journaled in,

end bearings 25, and is equipped with two.

sets of transmission gears, one for eachdrivefiflo..

. -the transverse shaft 24 by mechanism comperforations 46, 46 provided for .hold the lever in adjusted position.

in complementary format the opposite side and here will not be described); The shaft adapted for adjustment on the extension operator adapt the tractor for use in 'con- 'nection with yarying widths of implements, V In converting the tractor for use with wheel. Referring to Figs. 7 and 8,.particularly, the details of these devices will be clearer. The two bevel gears 26, 27 are slidable on the shaft 24 through the medium of the yoke 28 which is connected to the gears by the spoolsor sleeves 29, and the gears are keyed to the shaft as indicated at .30. The. yoke and its gears may be moved laterally from the lever 31 which is provided with the usual detent 32 to engage the rack 33 tfiid etween the two gears 26 and 27 and adapted to mesh with either of said gears is located the larger gear 34, journaled on the shaft 35. This longitudinal counter shaft 35 is sup-V ported in bearings 36 one each on the deck 9 and the other one on one of the bars 8 of the transverse frame. The rear end of the counter shaft 35 is equipped with a bevel gear 37 meshing with the complementary gear 38 onthe driving shaft 39 which is journaled in bearings 40 and 41. Through the medium of the sprocket wheel'42, chain 43, and sprocket wheel 44, attached to the wheel 2, the la'tter wheel is driven, to propel the vehicle over the ground.

The above described mechanism is shown of the vehicle to actuate the wheel 3 through the driving shaft 39 (which is driven from plementary to that which actuates shaft 39 39 actuates the wheel 3 through the sprocket ings 40, 40 are secured on the end of the main frame 6, out the outer bearings 41, 41 are secured on cross plates 45, 45'. which are frame 8 and may be secured thereon .by means of bolts passed through the series of '1 the purpose. The sprocket wheels, 42 42 are keyed on their respective shafts 39 39', and may slide inwardly or outwardly with relation to the bearing 40 or 40, and secured in adjusted position by a set screw 47.

The extension frame and adjustable plates and bearings supported thereby, enable the the body and rear wheels of a wagon as in ported on thepipe roller of the bolster 51.

In Figs. 12, 13, 14, 15 the tractor or drive wheels 2 and 3 have been detached, and the comparatively small wheels 52 of the mowing machine are driven from the sprocket wheel, as 42'. Again, the grain, drill of Fig. 13, the hay rake of Fig. 14 and the roller of Fig. 15 are each driven from the sprockets42 and 42 by means of their respective wheels 53, 54, and the roller 55. The independent drive of the separate wheels 2 and 3 enables the operator to make a short turn when driving. Thus, by throwing in or out the transmission gearing, the wheel 2 may be driven forward, and the wheel 3 be driven backward, or one wheel may remain impotent while the other is driven in either direction.

By moving the sprocket wheels on the shafts 39 39, and if necessary the bearing supporting plates 45 45', the chains'43 and .43 may be placed around sprocket wheels on traction wheels of greater or less tread or gage, as ,will be understood. The front wheels 1, 1, are purposely made small in diameter in order that they may pass under the fr me 6. The sprockets 44, 44" are portable, a d may beattached to any of the wheels 52, 53, 54, or, roller 55. Having thus described my invention, what I claim is The combination in a tractor of a front frame and a motor supported'thereon, a rear frame having traction wheels with driving verse bars connectingsaidframes and extending beyond the'sides of the frames, a transmission shaft on the front frame actu sprockets, and a pair of intermediate transated from the motor, a pair of independent f counter shafts actuated from the transmission shaft, 9, driving shaft for each countershaft operativelyponnected to the sprocket wheels. and eachlsaid driving shaft having a bearing In testlmony whereof I afiix in presence of two witnesses.
